🧠 Introduction to Various Processors – Trade Theory for COPA

The processor, also known as the CPU (Central Processing Unit), is the brain of the computer. It processes instructions and manages all operations inside a computer. Over the years, processors have evolved significantly in terms of speed, efficiency, and architecture.

In this lesson, you will learn about different types of processors and their uses.


🔍 What is a Processor?

A Processor (CPU) is a microchip inside a computer that executes instructions from software and hardware. It performs calculations, logic operations, and controls the data flow between memory and peripherals.


🧩 Basic Components of a Processor

  • ALU (Arithmetic Logic Unit): Performs arithmetic and logical operations

  • CU (Control Unit): Directs operations of the processor

  • Registers: Small memory units for quick data access


⚙️ Types of Processors
